Add .ksyms kfunc relocation support

Rewrite .ksyms kfunc extern calls to call_btf during ELF relocation via platform callback resolution and preserve module offset in IR marshal/unmarshal.

Changes:
- Add platform callback (resolve_ksym_btf_id) for symbol-to-{btf_id,module} resolution
- Pre-parse .BTF .ksyms function symbols and cache resolution in ELF loader
- Rewrite CALL src=1 externs to CALL src=2 with imm=btf_id and offset=module
- Preserve module offset in call_btf IR/marshal/unmarshal/printing
- Add negative-module validation and offset==0 precondition in rewrite
- Add focused tests for loader, marshal, and platform behavior
